The invention discloses a production process for disassembly forming of a ceramic pedestal pan, which comprises the following process steps of: mould design; slip casting; die sinking and drying; billet adhesion; and glazing and sintering. The product qualification rate of the ceramic pedestal pan produced by the process can reach over 85 percent; and the pollution discharge and water conservation of the product meet and even exceed the standard of national water-saving products.

The invention discloses a multipurpose boat for powder metallurgical sintering, which comprises a disk-shaped graphite boat body surrounded by a side wall and a base plate, wherein a plurality of grooves for accommodating the strip-shaped powder metallurgical sintering body are formed outside the base plate of the graphite boat body. The multipurpose boat for powder metallurgical sintering has the advantages of simple structure and wide application range, and is capable of reducing the handling cost of material. The invention further discloses a multipurpose boat unit which is made by overlapping more than two boats.

The invention relates to the technical field of a concrete block, in particular to an autoclaved aerated concrete block and a preparation method thereof. The autoclaved aerated concrete block is prepared by mixing calcium materials, siliceous materials, stir-fried plaster, a gas forming agent and phosphorus-containing waste slag and sequentially performing casting, still standing, cutting and autoclaved caring. Through the reasonable proportioning and process control, the internal and external quality of the product are improved; the consumption of lime and cement is reduced; the production cost is directly reduced; the still standing time is shortened; the production efficiency is improved.

The invention discloses high-brightness finishing printing silica gel for silk screen printing. The high-brightness finishing printing silica gel is prepared from the following raw materials in parts by mass: 10 to 15 parts of a high-brightness finishing printing silica gel component A and 1 to 3 parts of a high-brightness finishing printing silica gel component B. The invention further discloses a preparation method of the high-brightness finishing printing silica gel for the silk screen printing. According to the high-brightness finishing printing silica gel and the preparation method thereof, the defects of the general bright finishing gel are overcome; the high-brightness finishing gel with an outstanding brightness effect, high debubbling effect, urgent baking resistance, and zero hard spots and bubbles on a baked product is prepared; the finishing gel can be used for large-pattern printing finishing, to meet the requirement for the flowability, and also used for small-pattern finishing, to meet the requirement for avoiding smudging of a fillet.

The invention relates to a resource recycling system for all underground sewage and solid waste in a residential area, which is characterized in that it includes a membrane enrichment unit, a garbage pretreatment system, and a supercritical reaction system arranged under the ground. The sewage treatment pool, garbage storage pool on the second floor, and the control system installed in the central control room on the ground. The control system includes sensors, on-site execution components, controllers, and upper computers. The on-site execution components are electrically connected to the controller. Sensors, controllers Signal connection with the host computer; sensors and on-site execution components are set on the oxidant delivery pipeline, fuel delivery pipeline, material delivery pipeline, reactor, gaseous product discharge unit, and liquid product discharge unit. The invention can treat sewage and solid waste at the same time, so that solid waste is no longer treated by incineration, reducing pollutant discharge, and realizes the control process of system start, stop, emergency stop process, temperature adjustment and pressure adjustment through the control unit, and the system runs The generated data can be effectively collected, stored and analyzed.

The invention relates to the technical field of magnetic proximity switches, in particular to a low-pressure injection molding magnetic proximity switch, which comprises a plastic box, a reed switch and an inlet and outlet lead, wherein an opening is formed in the upper end of the plastic box; two threading slots are formed in the right end wall of the plastic box; a wire fixing pinch plate is arranged at the inner side of the left end wall of the plastic box; the wire fixing pinch plate is matched with the lateral wall of the plastic box to form a wire fixing opening; the inlet and outlet lead is electrically connected with two pins of the reed switch respectively; one pin of the reed switch is fixedly arranged in the wire fixing opening; and the inlet and outlet lead is transversely led out from the corresponding threading slot. The low-pressure injection molding magnetic proximity switch is reasonable in structure; one pin of the reed switch is integrally connected with the lead through a rivet; the electric connection strength is high; and the performance is stable. The rivet at one end of the reed switch is arranged in the wire fixing opening in a penetrating manner; the other end of the reed switch is limited through the positions of a wire clamping hole and a rib plate, so that the assembly position of the reed switch in an inner cavity of the plastic box is reasonable; a low-pressure injection molding process is achieved; and the impact strength and the electrical stability of the reed switch can be effectively improved.

The invention discloses an inorganic-polymer mud solidification mortar and a preparation method thereof. The preparation method comprises the following steps: subjecting heavy metal-containing mud produced in offshore engineering to physical-chemical treatment so as to obtain mud particles; then dissolving fly ash in a solution of soluble glass exciting agent, adding the treated mud and stone flour and carrying out mixing under stirring; and adding solid calcium oxide and carrying out stirring. The preparation method provided by the invention overcomes the disadvantage that a great amount of cement is needed in preparation of traditional cement mud solidification materials, reduces influence of production of greenhouse gases like CO2 and discharge of industrial dust in cement production to environment, makes full use of industrial waste like fly ash and waste stone flour for preparation of the mud solidification mortar and enables the industrial waste to be fully recycled and reused; through addition of solid calcium oxide, unwanted free water in the mixture is absorbed and the hydration reaction of an inorganic polymer is accelerated; and the inorganic-polymer mud solidification mortar has excellent early-stage mechanical properties.
